Oregon will head into the 2014 season with one of the Heisman Trophy front-runners and a possible early 2015 NFL Draft pick at quarterback in Marcus Mariota.

If he gets hurt, however -- as he did last season when he sprained the MCL in his knee -- things could get interesting for the Ducks thanks to a lack of depth behind him.

Backup quarterbacks Damion Hobbs and Jake Rodrigues have both reportedly transferred from the program this month, and the latter has already found a new home at San Diego State, according to the San Diego Union-Tribune.

Rodrigues was ranked as Rivals' No. 5 pro-style quarterback coming out of high school in 2012 and was a competitor in the prestigious Elite 11 competition prior to his senior year. He redshirted his first season in Eugene but saw action in seven games in 2013, going 3-for-6 for 67 yards and a touchdown with one interception. Following a tough battle to become Mariota's backup in the spring, Rodrigues lost out to redshirt sophomore Jeff Lockie and opted to transfer.

The moves leave the Ducks perilously thin on triggermen for their trademark up-tempo offense. Lockie has only thrown 13 passes in game action and is still an unknown quality after seeing little playing time so far. Redshirt freshman Taylor Alie, a walk-on, figures to be third in line at quarterback until four-star recruit Morgan Mahalak joins the squad in the fall.

The 6-foot-4, 218-pound Mariota threw for 3,665 yards last season while posting a 31-4 touchdown-to-interception ratio. He spurned the 2014 NFL Draft and opted to return to school as a redshirt junior but was considered by some analysts to be an early pick had he come out.
